Subject: [PATCH v8 2/4] dt-bindings: display: hdmi-connector: Support DDC bus enable
Date: Tue, 6 Aug 2019 17:57:41 +0200 [thread overview]
Message-ID: <20190806155744.10263-3-megous@megous.com> (raw)
In-Reply-To: <20190806155744.10263-1-megous-5qf/QAjKc83QT0dZR+AlfA@public.gmane.org>
From: Ondrej Jirman <megous-5qf/QAjKc83QT0dZR+AlfA@public.gmane.org>
Some Allwinner SoC using boards (Orange Pi 3 for example) need to enable
on-board voltage shifting logic for the DDC bus using a gpio to be able
to access DDC bus. Use ddc-en-gpios property on the hdmi-connector to
model this.
Add binding documentation for optional ddc-en-gpios property.
